Two of the five new species ( C. abyssus and C. circumaurea ) are each described from specimens taken at a single locality within the Caroline Islands (Palau and Yap, respectively); one ( C. degruyi ) is described from specimens collected or observed throughout the Caroline Islands, and two ( C. brevirostris and C. earina ) are described from specimens collected from several localities throughout the Caroline Islands, Fiji, and Vanuatu. All five species can easily be distinguished from other known Chromis , and from each other, on the basis of color and morphology. These new species represent the first five scientific names prospectively registered in the official ICZN ZooBank registry6. Moreover, the electronic online edition of this document has been specially formatted with many embedded links to additional resources available online via the internet to enhance access to taxonomically-relevant information, and as a demonstration of the utility of international standards for biodiversity informatics. Key words: Chromis abyssus , Chromis brevirostris , Chromis circumaurea , Chromis degruyi, Chromis earina , new species , taxonomy, cybertaxonomy, mesophotic, mixed-gas diving, rebreather, ZooBank Introduction Over the past two decades, the authors have developed and refined techniques for using advanced dive gear and various gas mixtures to allow safe excursions to depths of 50-150 m, which exceeds the depths that can be safely reached using conventional SCUBA. Initial exploratory deep dives by the authors at various localities throughout the tropical Pacific have revealed a rich diversity of coral-reef-associated fishes inhabiting Accepted by L. A. Rocha: 11 Dec. 2007; published: 1 Jan. 2008 3 urn:lsid:zoobank.org:pub:68376390-7809-46FF-9EC4-1371B4AAD0FF these depths (Pyle 1996a, 1996b, 1999, 2000). In addition to the discovery of many new species of fishes, initial exploration of deep coral reefs (sometimes referred to as "mesophotic" reefs) has led to new insights concerning ecological and biogeographic processes in both the Pacific (Pyle 2000, unpublished data) and the tropical Atlantic (Feitoza et al. 2005). The pomacentrid genus Chromis Cuvier 1814 (type species Sparus7 chromis8 Linnaeus 1758) is the largest genus of the family, with 86 valid species. Fishes of this genus are among the few pomacentrid species known to inhabit deep coral reefs, perhaps a reflection of their principal food (zooplankton), in contrast to species of genera that are dependant primarily on benthic algae. At least 34 species of Chromis are known to inhabit depths of 50 m or more, but only nine are restricted to such depths, and only five ( C. okamurai 9 Yamakawa and Randall 1989, C. mirationis 10 Tanaka 1917, C. struhsakeri 11 Randall and Swerdloff 1973, C. abyssicola 12 Allen and Randall 1985, and C. onumai 13 Senou and Kudo 2007) are known only from depths of 60 m or more. Except for two specimens of C. brevirostris collected at a depth of 60 m, all specimens of the new species described herein were collected at depths of 85 m or more. Whereas the print (paper) edition of this article represents the publication through which these five new scientific names are made available under the current (4th Edition) International Commission of Zoological Nomenclature (ICZN)14 Code of Nomenclature15, the concurrently distributed electronic online edition is intended to exemplify the utility of modern international biodiversity informatics standards. Symbolically published on the 250th anniversary of the officially recognized date of publication of Systema Naturae (Linnaeus1758), it is our hope that this article will help demonstrate the value of electronic informatics standards in enhancing the work of all taxonomists throughout the next quarter-millennium and beyond. Material and methods Specimen collection and deposition All specimens were collected with hand nets (sometimes with the aid of rotenone or quinaldine sulphate) by divers using Cis-Lunar® MK-5P mixed-gas, closed-circuit rebreathers, generally following protocols outlined by Pyle (1996c). In all cases, specimens were collected in full accordance with local government regulations, and in compliance with appropriate animal care standards. Most specimens were photographed when fresh, usually following the technique described by Randall (1961). Before exposure to formalin, tissue samples(usually the right pelvic fin) were removed from many specimens and stored in vials containing DMSO for later analysis. Holotypes of C. abyssus, C. brevirostris, C. circumaurea, and C. degruyi are deposited in the fish collection of the Bernice P. Bishop Museum, Honolulu (BPBM)16; the holotype of C. earina is deposited in the fish collection of Museum National d'Histoire Naturelle, Paris (MNHN)17. Paratypes are deposited in these two insitutions, as well as The Natural History Museum, London (BMNH)18; California Academy of Sciences, San Francisco (CAS)19; United States National Museum of Natural History, Washington, D.C. (USNM)20; and the Western Australian Museum, Perth (WAM)21. Tissue samples were deposited for long-term cryogenic storage at the Pacific Center for Molecular Biodiversity (PCMB)22, located at BPBM. All of these collections have been registered with the Biodiversity Collections Index (BCI)23. Counts, measurements and molecular analysis Counts of median fin rays, vertebrae, and predorsal bones were taken from digitally-scanned radiograph images ("x-rays")24. Measurements of standard length (SL), lengths from tip of snout to origins of dorsal, pelvic and anal fins, dorsal- and anal-fin bases, and dorsal- and anal-fin spine lengths of specimens not bent or otherwise distorted were calculated to the nearest tenth (0.1) of a mm from radiograph images25, and verified against measurements taken directly from specimens. All other counts and measurements were taken directly from specimens using a Fowler® Ultra-Cal IV 300-mm digital caliper. Measurement values were recorded to the nearest hundredth (0.01) of a mm, but rounded to the nearest tenth (0.1) of a mm for analyses. Methods of counts and measurements are mostly consistent with those described in Allen & Randall (2004). Unless otherwise indicated, specimen lengths are SL26, measured as the straight-line distance between the anteriormost tip of the upper lip and the posterior edge of the hypural plate; head length27 is between anteriormost tip of upper lip and posterior edge of opercle flap; body depth28 is maximum vertical distance between belly and base of dorsal spines; body width29 is maximum width posterior to opercular opening; snout length30 is straight-line distance from anteriormost tip of upper lip to closest point on anterior fleshy edge of orbit; orbit diameter31 is horizontal fleshy diameter; interorbital width32 is least bony width between eyes; upper jaw length33 is straight-line distance from anteriormost tip of upper lip to ventroposteriormost tip of maxilla; caudal peduncle depth34 is least depth; caudal peduncle length is horizontal distance between verticals at posterior base of anal fin and posterior edge of hypural plate35; fin spine36 and ray37 lengths are straight-line distances between extreme base and distal tip (including filamentous extension, if any); caudal fin length38 is horizontal distance from posterior edge of hypural plate to a vertical at distal tip of longest ray (including filamentous extension, if any); caudal concavity39 is horizontal distance between tips of the shortest and longest rays; pectoral-fin length40 is length of longest ray; pelvic fin length41 is length of longest ray; pectoral-fin ray count42 includes small splint-like, uppermost rudimentary ray; lateral-line scale count43 includes only those scales with tubes; a separate count is provided for pored or pitted scales occurring midlaterally on caudal peduncle44; scale-row counts above45 and below46 lateral line to origins of dorsal and anal fins (respectively) with values that include ".5" refer to small truncate scales (if any) at bases of respective fins; gill-raker counts47 include all rudiments and are provided as separate values for upper and lower limbs of first gill arch; last fin ray of dorsal and anal fins sometimes branched at or near extreme base and counted as a single ray, but only when connected at or near the extreme base48 (otherwise counted as two49). Unless otherwise indicated, measurements provided in the text represent proportion of SL. Measurements provided in the tables represent percent of SL. Counts, measurements and proportions appearing in parentheses represent ranges for paratypes, if different from the holotype. Counts represented as two values separated by a pipe "|" represent values taken from left|right sides of specimens. Total genomic DNA was extracted from available tissue samples using the Qiagen Dneasy® tissue kit following the manufacturer's protocol. In compliance with the Barcode of Life initiative, a fragment of the cytochrome oxidase I (COI) gene from the mitochondrial DNA (mtDNA) was amplified for holotypes (and some paratypes) of all species. Primers used for amplification and sequencing were BOL-F1 (5' TCA ACY AAT CAY AAA GAT ATY GGC AC 3') and BOL-R1 (5' ACT TCY GGG TGR CCR AAR AAT CA 3'), modified from Wa r d et al. (2005). Each PCR had a total volume of 25 µl, containing between 10-20 ng of purified DNA, 2.5 µl of 10x reaction buffer, 1.5 µl of 8 mM pre-mixed dNTPs, 2.5 mM of MgCl2, 0.25 µM of each primer and two units of Taq DNA polymerase (Promega, Madison, WI). Cycling parameters for the mtDNA were as follows: initial denaturation at 94°C for 2 min; 35 cycles of 94°C for 45 sec, 50°C for 45 sec, 72°C for 55 sec; and a final extension at 72°C for 2.5 min. The resulting reaction was purified with exonuclease I and shrimp alkaline phosphatase enzymes. Excess oligonucleotide primers were removed through simultaneous incubation of PCR product with exonuclease I and shrimp alkaline phosphatase (USB Corp., Cleveland OH). Because of a broader ongoing effort by Luiz Rocha and colleagues to analyze phylogenetic patterns of species within the genus Chromis , no attempt is made to infer evolutionary affinities of these five new species, other than qualitative discussions about similarities with other species, if relevant. Electronic content and hyperlinks The online edition of this article includes extensive use of "hyperlinks" (embedded links that allow simple redirection to online documents and resources via the internet). When viewing this online edition using hyperlink-enabled software, clicking on the hyperlink text (dark blue in color) using the computer mouse pointer will redirect the reader to the hyperlinked location or resource. There are two general categories of such hyperlinks: internal, and external. Internal hyperlinks are used for linking between taxon names included within this text and the full treatment (or first mention) of those taxa elsewhere within this document. Similarly, internal hyperlinks are used for linking between literature citations in the text and the corresponding full bibliographic citations in the "References" section of this aritcle. External hyperlinks are used for linking portions of this document to electronic resources and information, such as online registration records of taxon names, taxon usage instances, natural history specimen collections, literature, data files, and images. All such external hyperlinks are denoted by a superscript number at their first use, corresponding to a Universal Resource Locator (URL) as listed in the "Embedded External Hyperlinks" Appendix at the end of this article. These URLs are included primarily to allow access to the online resources from the print edition, when the online edition is not available. Whenever possible, information made accessible through external hyperlinks conforms to current standards and protocols as developed and maintained through Biodiversity Information Standards (formerly Taxonomic Databases Working Group; TDWG50). Most external hyperlinks are represented as a Life Science Identifier (LSID51) enclosed within an HTTP proxy (to allow viewing through standard web browsers), but others represent direct HTTP URLs or other standard protocols (e.g., "mailto"). All five new species names established herein have been prospectively registered in ZooBank (Polaszek et al. 2005a; 2005b), the official online registration system for the ICZN, which was launched the same day this article was published. All other scientific names mentioned in this article have been retrospectively registered in ZooBank, and hyperlinks are directed to Taxon-Name Usage records, most of which represent taxonomic concepts corresponding to those names as asserted herein. An Appendix at the end of this article lists most of the URLs, which are included for the benefit of readers of the print edition. Excluded from the Appendix are all internal hyperlinks, the three "mailto" hyperlinks associated with the email addresses of the authors, the ZooBank publication LSID for this article that appears on the bottom of the first page, and the embedded hyperlinks associated with the five ZooBank LSIDs for the new species described herein (all six ZooBank LSIDs can be viewed through any standard web browser by appending the LSID to the prefix "http://zoobank.org/"). DNA Barcodes have been deposited in GenBank52, in compliance with the Barcode of Life Data Systems (BOLD)53 and associated Fish Barcode of Life Initiative54, and are accessible through hyperlinks associated with PCMB numbers for each specimen. Images included in this article, as well as other relevant images, have been made available through Morphbank55. Holotypes of C. abyssus and C. degruyi were scanned at the University of Texas High-Resolution X-ray CT Facility, and visualizations of those scans were provided by the Digital Morphology (DigiMorph)56 project. References cited in this document are registered with ZooBank6, and are available as full-page images through the Biodiversity Heritage Library (BHL)57 when copyright allows. Descriptive data concerning type specimens of the five new species are available through the TDWG- compliant Structure of Descriptive Data (SDD) standard. The content of this article is available as marked-up text using the TaxonX58 and taXMLit standards.

Color in alcohol similar to general color pattern when fresh, except charcoal gray pigment sometimes fades to brownish gray, and iridescent dark blue is either faded to pale gray blue, or has disappeared altogether (leaving the specimen uniform brownish gray, or sometimes charcoal gray overall). Distribution. Only collected from the type locality; also observed at similar depths at Augulpelu Reef in Palau. An individual of what appears to be this species was observed and photographed by Mr. Forrest Young at 120-150 m near Manado, Sulawesi, Indonesia. Etymology. Named abyssus , a Latinized form of the Greek noun abyssos (meaning "abyss"), to honor the documentary film Pacific Abyss, produced by the British Broadcasting Corporation (BBC), which funded the expedition on which the type specimens were collected. The vernacular name "Deep Blue Chromis ", a reference to both the life color of this species and the relatively (within the context of the genus) deep-dwelling habits, is suggested instead of the more literally translated "Abyss Chromis ", so as not to imply that the species inhabits depths commonly defined as "abyssal". Remarks. This species was first observed by the senior author on May 10, 1997, during a mixed-gas rebreather dive to 120 m on the east side of Augulpelu Reef; Palau (07º 16.41' N, 134º 31.44' E). It was later observed at the same reef at depths of 117-139 m from a submersible by Patrick L. Colin and Lori J. Bell in February -March, 2001. In April 2005, Mr. Forrest Young and colleagues observed several individuals of this (or a very similar) species during mixed-gas rebreather dives at depths of 120-150 m at Manado, Sulawesi, Indonesia. The type specimens included herein are the first of this species to be collected. From these observations, C. abyssus appears to prefer depths in excess of 115 m, staying close to the substratum among boulders and rock outcroppings, where it takes refuge in small caves and holes. Juveniles and some subadults were also observed around limestone talus. Adults were usually observed singly or in pairs, while subadults and juveniles were seen in small groups. All type specimens were collected in the same general area, where the species is not uncommon. Other Chromis observed in the vicinity include three of the new species described herein ( C. brevirostris, C. degruyi , and C. earina ). Chromis abyssus is not obviously allied with any other known species of the genus. It shares some similarities with a group of seven Indo-Pacific deep-dwelling Chromis species, characterized by a similar stout body shape, a large eye, and usually XIV dorsal spines. In their 1985 description of C. abyssicola, Allen and Randall noted a complex of deep-dwelling Chromis species distinguished by, among other characters, 19 or 20 pectoral rays, and 28-34 gill rakers. In addition to C. abyssicola , their complex included C. megalopsis 78 Allen 1976 (now regarded as a junior synonym of C. mirationis Tanaka 1917), C. mirationis Tanaka 1917 and C. struhsakeri Randall and Swerdloff 1973, to which we would add the subsequently named C. planesi 79 Lecchini and Williams 2004. C. abyssus has fewer pectoral rays (18 or 19) and fewer gill rakers (24-28) than members of this species complex, and may comprise a second grouping of deep-dwelling Chromis species, along with C. okamuri Yamakawa and Randall 1989 from Japan, the East African C. woodsi 80 Bruner and Arnam 1979 (both easily distinguished from C. abyssus on the basis of color and certain morphological characters such as number of gill rakers and tubed lateral-line scales), as well as the two new species C. circumaurea and C. degruyi , both described herein. Of the remaining two deep-dwelling Indo-Pacific stout-bodied Chromis species with XIV spines, C. onumai Senou and Kudo 2007 has the high pectoral-ray count of the first complex (19-20) and the gill-raker count of the second (25-27). C. axillaris 81 (Bennett 1831) has a wide gillraker range (26-30) and cannot easily be placed in either complex by this character. Of the three new Chromis with XIV dorsal-fin spines described herein (C. abyssus, C. circumaurea, and C. degruyi ), each has a unique and distinctive color pattern, and is readily distinguished from the others. Among the three, the former two ( C. abyssus and C. circumaurea ) share the most similarities both in terms of morphology and in Barcode DNA sequence data.

Distribution. This species has been observed or collected from the Marshall Islands southward to Fiji, across the Caroline Islands from Puluwat to Palau, and south to Vanuatu. An underwater photo of what seems to be this species (or an undescribed species very similar to C. brevirostris ) taken in Bali, Indonesia, appears as " Chromis sp." on p. 531 of Kuiter & Debelius, 2006. C. brevirostris was not observed at Rarotonga (Cook Islands), Kiritimati (Line Islands), or American Samoa during brief surveys of deep reefs at those localities. Etymology. Named brevirostris , an adjective derived from the Latin words brevis (meaning "short") and rostrum (meaning "beak" or "snout"), in reference to the very short snout of this species relative to other species in the genus. Remarks. Generally abundant in its typical environment, which is characterized by steep slopes and drop-offs at depths of about 90-120 m. Usually found in association with small holes and limestone talus, often in aggregations ranging from a half-dozen to several dozen individuals feeding low in the water column. Chromis brevirostris , as well as the new species C. earina (described herein) are both deep-dwelling Chromis species with XIII dorsal spines, a deep body (1.57-1.9 in S.L.), short snout (3.45-4.8 in head), and large eye (2.0-2.6 in head). Most counts are similar, and these two species appear to have more affinities with each other than with any other species in the genus. They can be readily distinguished from each other on the basis of color and by differences in general body shape (particularly the shape of the head profile, which is smoothly convex in C. brevirostris , as opposed to slightly concave dorsal to the eye in C. earina ), and dorsal- and anal-fin soft ray counts. Chromis brevirostris has 13-14 dorsal-fin soft rays and 15-16 anal-fin soft rays (except for one deformed individual with only 13 anal-fin soft rays); whereas C. earina has 11-12 dorsal-fin soft rays and 12 anal-fin soft rays. Table 3 lists selected characters for four Indo-Pacific Chromis species which seem to be most similar to C. brevirostris and C. earina . These four species, including C. alpha 101 Randall1988a, C. nigroanalis 102 Randall 1988b, C. ovatiformis 103 Fowler 1946, and C. pembae 104 Randall and McCosker 1992 (which we collectively and informally refer to here as the " Chromis alpha complex") all have XIII dorsal spines, a roughly similar body shape, and have been recorded at a depth of 40 m or greater. For each of these species, at least one count, and all gill raker counts, range outside the respective ranges for C. brevirostris and C. earina .

Color in alcohol similar to fresh color, except yellow portions are much paler yellow, and brown portions are slightly paler brown (much paler brown on thorax). Distribution. Observed from submersibles in the Marshall Islands and Mariana Islands, but only collected from Yap. Etymology. Named circumaurea , an adjective derived from the Latin words circum (meaning "around") and aurea (meaning "golden, of gold"), in reference to the golden-yellow anal fin, caudal fin, and outer margin of the dorsal fin. Remarks. This species was first observed and photographed from a submersible by Patrick L. Colin at Enewetak in the Marshall Islands. An unconfirmed sighting and video clip of this species from the Mariana Islands requires verification. It was observed at Yap at depths of 98-120 m, in a group of about a dozen individuals living among large (~1-2 m) rock boulders just above the upper edge of a precipitous drop-off. A juvenile of approximately 40 mm SL was observed by the first author at a depth of 120 m, below the site where the type specimens were collected; its color pattern was consistent with that of the adults. Two photos appearing on p. 390 of Kuiter & Tonozuka (2001), labelled as Chromis analis 120 (Cuvier 1830), bear a remarkable resemblance to C. circumaurea , but differ in number of dorsal-fin spines (XIII vs. XIV) and color of body (paler in C. analis ), caudal peduncle (dark centrally vs. entriely yellow), and central region of caudal fin (transparent vs. yellow). This species also bears a superficial resemblance in color to Chromis flavicauda121 (Guenther 1880) from the western Atlantic Ocean, but is readily distinguished from that species on the basis of body color (blue in C. flavicauda vs. brown in C. circumaurea ), dorsal-fin rays (XIII,11-12 vs. XIV,12-13, usually 13), anal-fin soft rays (11 vs. 13). Similarities with other deep-dwelling species with XIV dorsal-fin spines, including the new species C. abyssus described herein, are discussed in the Remarks section of C. abyssus .

Color in alcohol similar to fresh color, except paler brown overall. Distribution. Observed or collected throughout the Caroline Islands, from Puluwat to Palau. A Chromis resembling the juvenile of this species was observed in Fagatele Bay in May 2001 by the senior author. Etymology. Named degruyi to honor Michael V. DeGruy, in recognition of the sincere enthusiasm and determination he demonstrated while attempting to collect the first adult specimen of this species. Remarks. The habitat of this species is similar to that of other species described herein: deep outer-reef slopes at depths of 85-120 m, usually in the vicinity of rock outcrops with small holes and caves, and around limestone talus. It is generally not as abundant as other species of Chromis described here, usually found in small groups and observed feeding low in the water column. The species appears most similar to other deep-dwelling species of Chromis described previously (see Remarks section of C. abyssus ). Juveniles superficially resemble C. opercularis 136 (Guenther in Playfair and Guenther 1867) in color, but are easily distinguished from that species on several morphological characters (e.g., usually XIV dorsal-fin spines in C. degruyi , vs. XIII in C. opercularis ; body depth 1.84-1.99 in SL vs. 2.1-2.3 in C. opercularis ), as well as adult coloration. Some aspects of the adult coloration are similar to C. planesi Lecchini and Williams 2004, but C. degruyi differs from that species in many other aspects of adult coloration as well as number of pectoral-fin rays (20 in C. planesi vs. 18 in C. degruyi ), dorsal-fin soft rays (usually 13 vs. usually 12), and tubed lateral-line scales (17 vs. usually 15-16).

Named earina , a Latinized form of the Greek adjective earinos (meaning "the color of spring", i.e., green), in reference to the pale green color of this species in life. Remarks. This species inhabits the same general habitat as the other new species described herein: steep outer reef slopes and drop-offs with rocky outcrops and small caves and holes, often in association with limestone talus. It is often observed in pairs or small groups, feeding low in the water column, and is generally abundant where it is found. Similarities with other species are discussed in the Remarks section under the account of C. brevirostris .
